3.5 - Chain-operated emergency manual device (KE 2)
The emergency manual device must only be used to open and close the door in the event of power outages.
WARNINGS:
- The emergency manual device must only be used when the motor is off.
- The emergency manual device must be operated in a safe place.
- The emergency manual device must never make the automation system exceed the end positions, as this would activate the emergency limit
switch. In this situation, the automation system cannot be activated electrically.
01. Disconnect the automation from the mains power supply
02. Grasp the 'HAND' grip and pull gently until it stops, thus cutting off
the control voltage and preventing the door from being activated
electrically.
